Shuttle.



an r. srmtcnia,

snurrraa manner.

This invention relates to certain new and useful lmprovements 1n shuttles, and relatesmore particularly to a threading device in which the thread is positioned adjacent to I head 1 connected by an inclined shank 2 tothe delivery eye, and is then positively The primary object of the invention is to provide improved means for effecting the stated threading of the shuttle, and to also provide a means for operating the plunger, which means is retained within a socket in the shuttle side or otherwise housed by the shuttle and which is automatically returned to such position after operation of the plunger.

The invention further consists in certain details of construction and combination of parts more fully hereinafter described and set forth in the appended claims.

In the drawings Figurel is a fragmentary view of a shuttle, in top plan View, having the present invention applied thereto. Fig. 2 is a sectionon the lme 2-2 of Fig. 3. Fig. 3 is a' section on the line 3-3 of Fig. 1. Fig. 4 is a detail perspective view of the plunger. Fi 5 is a detail perspective View of the element which operates the plunger, and Fig. 6 is a plan view of the blank from which the stationary threading member is formed.

In proceeding in accordance with the present invention a stationary threading member is employed which consists .of a

a base 3, which latter is also horizontally disposed and is formed with a vertical guiding wall 4 which is inset in the adjacent side wall of the'shuttle throat and isrounded so as to guide the thread from the bobbin. The base l-is also provided with a second side guiding wall 5 which is vertically disposed and is'rounded and located adjacent to the delivery eye D, so that the thread will pass diagonally across the space between the two walls I and 5 as depicted in Fig. .1 of the drawings.

Depending from the base'3is an arm 6 provided with a slot '8 which lat're specification of Eettera Patent. Application mean-m as, lei-a. Serial 1%. career.

with the delivery eyeD, which slot 'acts as a guide or bearing for the reciprocal threading plunger 8 which plunger slides through the slot 17' and through the delivery eye D so as to feed the thread through the eye D. The'free end of the plunger 8 is forked at 9 so as to engage with the thread. The rear,

end of the plunger is turned at'right angles and formed with a rounded head 10 slotted at 11, the head 10 sliding in an opening 12 provided for the reception thereof in the The plunger is moved to threading posi-- tion by means of a finger engaging-member which consists of a strip of metal bent into substantial lU-form so as to have an outer leg 13 and an inner leg 14, the latter being curved and contracted at its free end portion at 15 to provide a shank which is receivable through the slot 11 of head 10, the

shank having a T shaped head 16, whereby the head 16 may be passed through the slot 11 and then turned to bring the longitudinal axis of the head at right angles to the longitudinal axis of the slot, so to thus provide a, movable connection between the plunger and the. operating member thereof. 1

lhe shank 15 of the operating member forms shoulders 17 which bear, against the outer face of head 10 and thus depress the plunger against the action of a coil spring 18 which exerts tension against the inner face of head 10, and normally-serves to hold the plunger in the out position shown in Fig. 2 of the drawings. A pin 19 is passed downwardly to ride on the shank 2' which brings the thread in the dotted line position shown in Figs. 2 and 3 of the drawings, 1n which position'the thread traverses the delivery eye and the slot 7 as shown in said Figs( 2 and 3 of the drawings, in dotted lines. be operating member of the plunger is then manually grip ed and moved to the dotted line position IOWD in Fig. 2, in which position the operating member 1s apparatus than that which it carries.

pushed thus causingthe leg 14 to ride the pin 19, and force the plunger 8 to a position in which its forked end 9 engages the thread and carries the latter in the form of a loop out through the delivery eye, in which position the thread is manually caught by the fingers of the operator and completely drawn through the delivery eye. Imme; diately upon release of the operating member the spring 18 will automatically return the plunger and the said member to the full line position shown in Fig. 2 in which position the operating member is fully and completely housed within the socket 20.

Thus in the operation of the shuttle the,

operating member of the plunger is housed completely within the shuttle and forms a part of the latter in so far as being carried thereby is concerned, which enables the entire threading apparatus to be carried by the shuttle at all times, and enables the shut tle to be threaded without the use of other The spring acts to not only restore the operating member to housed'position, but to also retain same in such position during the shuttle movements and the pin 19 acts to prevent the operating member from flying outwardly during the shuttle action.

aving thus described my invention, 1 claim as new and desire to secure by Letters Patent' I. In a shuttle threading device, in combination with the shuttle having a delivery eye, and means to enable'the thread to be placed in aposition where same traverses the eye, a'plunger having a forked free end and havinga right angular slotted head on its opposite end, which head operates in a guide opening provided therefor in the shuttle, a spring in said opening normally moving the plunger outwardlyaway from the delivery eye, a U-shaped operating memher having one of the legs thereof contracted at its free end' portion to provide shoulders which bear on the outer face of the head and having a T-shaped head, saidicontracted portion being curved to enable the T-shaped head to be passed through the slot of the head so as to movably connect the plunger and operating member, and a pin engaged between the legs of said member, said shuttle having a socket in which the operating member is completely housed and retained by said spring.

2. In a shuttle threading device, in combination with a shuttle having a delivery eye, means to enable the thread to traverse the eye, the shuttle also having a socket in one side thereof, a spring pressed plunger for forcing the thread through the eye, and an operating member connected to the plunger and normally occupying a position at right angles to the plunger and within the socket and having its outer end free and movable in the arc of a circle.

3. In combination with a shuttle having a delivery eye, a socket and means to enable the thread to be moved to a position in which same traverses the eye, means to force the thread through the eye, means to operate said forcing means having its outer end free so as to move into and out of the socket and movably connected thereto, and means whereby said operating means upon completion of its action on the forcing means'will be automatically placed within the socket.

{1. In combination with a shuttle having a delivery eye, a spring tensioned depressible means to force thethread through the eye, a member engaged at one end with said means to depress same and having its opposite end free and movable toward and away from the shuttle, and means to engage said member to guide same whereby upon movement thereof away from the shuttle and subsequent release the depressible means will automatically move said member toward the shuttle.
